Hi, Timothy,
See my reply on the other thread. I guess I'm not as active in the
newsgroups these days ... sometimes that happens.

Hi Christian,
no problem, i even just thought, that it wasn't recognized as an
question, but as an answer.
I ran this junit test as an junit plugin test, so within the eclipse
context. I even checked, whether i have referenced the required plugins.
See the list:
org.eclipse.emf;bundle-version="2.4.0",
org.eclipse.emf.ecore;bundle-version="2.4.2",
org.eclipse.emf.ecore.xmi;bundle-version="2.4.1",
org.eclipse.ocl;bundle-version="1.2.3",
org.eclipse.ocl.doc;bundle-version="1.2.1",
org.eclipse.ocl.ecore;bundle-version="1.2.1",
org.eclipse.ocl.source;bundle-version="1.2.3",
org.eclipse.ocl.uml;bundle-version="1.2.3",
org.eclipse.ocl.uml.source;bundle-version="1.2.3",
org.eclipse.pde.runtime;bundle-version="3.4.0",
org.eclipse.uml2;bundle-version="2.1.0",
org.eclipse.uml2.common;bundle-version="1.4.0",
org.eclipse.uml2.uml;bundle-version="2.2.2",
org.eclipse.uml2.uml.resources;bundle-version="2.2.0",
But the following snippet still doesn't work:
final Resource oclResource =
ocl.getEnvironment().getTypeResolver().getResource();
oclResource.setURI(outURI);
try {
oclResource.save(null);
} catch (IOException e) {
e.printStackTrace();
}
Thx Timothy

Hi, Timothy,
You might try comparing your code against what the
org.eclipse.ocl.uml.SerializationTest does, to see what you might be
missing. It isn't readily apparent to me.
It is interesting that the problem is with the ExpressionInOcl type.
This is one of very few cases where MDT OCL uses a Java-conventional
name for the EClass ("ExpressionInOCL" -- note the capital "CL") and
uses extended metadata to apply the OMG-defined name "ExpressionInOcl"
in the XMI serialization. Perhaps there is something amiss in the
ExtendedMetaData in your scenario? I would debug the look-up of the
EClass name in the deserialization to find out ...
HTH,
Christian

Hi, Timothy,
Just check out the test project from the CVS repository:
/cvsroot/modeling/org.eclipse.mdt/org.eclipse.ocl/plugins/or g.eclipse.ocl.uml.tests
Cheers,
Christian
